She should have let him finish his objection, instead of interrupping him.
From what I saw, is that him not being allowed to finish his objection is why he continued doing so; because if Zimmerman is convicted, and it's appealed, all the objections have to be concise to what the objection is, or else they aren't allowed.
I thought she did, but if she did not, then you are correct, he should be allowed to finish all objections on the record
